♥♥♥ HACKER REFLECTION ♥♥♥

          In 1988, Dade "Zero Cool" Murphy (age 11) is arrested and charged with crashing 1,507 systems in one day and causing a single-day 7-point drop in the New York Stock Exchange. Upon conviction, he is banned from owning or operating computers or touch-tone telephones until his 18th birthday.

         As he turn 18, his mothertakes a job in New York City. Dade calls a local television station, dupes the security guard into giving him the modem's phone number  and successfully hacks into the station's computer network, changing the current TV program to an episode of The Outer Limits. However, Dade is "attacked" by a hacker (handle"Acid Burn") on the same network. During the conversation, Dade identifies himself by the new alias, Crash Override.

           Dade enrolls at Stanton High School, where he meets Kate Libby (Angelina Jolie), who is assigned to take him on a tour of the school. After Dade learns that Kate is "Acid Burn", a feud erupts between them.

           The real trouble begins when Joey Pardella, the novice hacker of the group, successfully breaks into an Ellingson Mineral Company supercomputer to prove to the rest of the group that he is an elite hacker. To validate this feat, he downloads part of a garbage file. Unfortunately, the company's IT employee Hal (Penn Jillette) detects this unauthorized entry and summons computer security officer Eugene "The Plague" Belford (Fisher Stevens) to deal with the problem. He realizes the file being downloaded can prove that The Plague is stealing from the company.

           Joey is arrested and his computer is searched, but the Secret Service finds nothing, as Joey has hidden the disk containing the files. After being released on parole, Joey reveals the disk to Phantom Phreak in a public park; but they quickly realize that they are being followed by the Secret Service. The next day, Phreak is arrested. He uses his phone call to inform Kate that he hid the disk in a boy's bathroom at school. That evening, Kate and Cereal Killer ask Dade for his help; but, because of his record, he declines. Kate then asks Dade to copy the disk so that, if anyone else is arrested, they have the disk as evidence.

          The next morning, they evade the Secret Service and converge on Grand Central station, where they use payphones to begin their assault on the Gibson. At first, their attempts are easily rebuffed by Plague, who calls Dade to warn him to escape before he is arrested. However, Razor and Blade have contacted hackers around the world, who lend their support with virus attacks, distracting Plague long enough for Dade to download the incriminating file to a floppy disk.

Shortly after crashing the Gibson, Dade and company are arrested. As they're being led away, Dade surreptitiously informs Cereal Killer, hiding in the crowd, that he's tossed the disk in a trashcan. As Dade and Kate are being interrogated, Razor and Blade jam the local television signals and broadcast live video of Cereal Killer, revealing the plot and Plague's complicity. Plague is arrested when he tries to flee to Japan. Their names cleared, Dade and Kate go on a date. Kate even wears a dress. While relaxing in a pool on the roof of a building, their friends show off their latest hack—the lights in several adjacent office buildings spell out "CRASH AND BURN."

REFLECTIONS:

This movie is a good fun time, with interesting characters and an intriguing story line. Although the technology is somewhat outdated it is easy to suspend belief and to become involved in the story.As someone who grew up with computers, and has a fairly well grounded background in the tech sector. I find this movie to be a classic tech flick, there are part that are cheesy. However I find that the story itself is solid. This is a movie I can watch over and over and never really grow board with it.

The term hacker is used in popular media to describe someone who attempts to break into computer systems. Typically, this kind of hacker would be a proficient programmer or engineer with sufficient technical knowledge to understand the weak points in a security system.

ACT-II •••(Source Code)•••

        Jake Gyllenhaal as Colter Stevens is an Army helicopter Pilot, he wakes up on a commuter train going to Chicago, but he doesn't  seem to know himself. When he on the bathroom mirror he saw a man  and he appears as Sean Fentress a school teacher. The woman his traveling partner named Christina Warren (Michelle Monaghan) seems to know him by the name Sean Fentress. After 8 minutes the bomb was explode in the train, killing everyone aboard and derailing it and a train travelling in the other direction. The mission og stevens was not successful using the Source Code and then, it was Flaskbacks/Alternate Timeslines.

Stevens awakes again with no memory and how he became involved in the source code projects. Stevens regains consciousness inside unfamiliar cockpit. Air force Captain Collen, Goodwin (Vera Farmiga) explain steven’s identity through a computer screen that he is colter stevens, she explain stevens is in the source code. Dr. Rutledge (Jeffry Wright) scientist for Beleaguered Castle (a military Unit named after the card named),he created the source code an experimental device, that allows its user to experience the last 8 minutes of another compatible person’s life within an alternate time. stevens last memory is he on helicopter on a mission in Afghanistan.

Stevens mission by using source code to discover the location of a bomb aboard the train and to know the bomber who detonated it. Goodwin explain to stevens the  train explosion occur that morning, and was a warning by the bomber as a precursor to a larger dirty bomb that would be detonated in downtown of Chicago and it can cause the deaths of Millions people. Through stevens actions cannot change the past and save the lives aboard the train, identifier the bomber in the alternate timeline will prevent the deaths of Millions people.

Stevens sent into the Source Code several more times and continues to rule out passengers suspected to be the bomber, he’s still finding the terrorist, as well as developing increasingly strong romantic feelings and empathy for Christina. Until the bomb explode and destroy the train again and Fentress dies, stevens send back to the chamber. Rutledge and Goodwin want to focus and keep on finding the bomber, when every time he sent into the Source Code, he remember the incident while on duty in Afghanistan that reportedly killed him. When stevens discover he verbally accost Goodwin for more information, she forced to explain the real life steven situation. Stevens make a deal to  complete the mission, if he complete the mission they terminate his life support after it is completed, then Dr. Rutledge agrees.

Stevens back in the Source Code, he eventually identifies the bomber named Derek Frost (Micheal Arden). Stevens mission was successful. Rutledge tells Goodwin to erased the memory of Stevens and renege in the deal so he can be used next mission. Stevens convince Goodwin to let him return to Source Code. One more time, after she will disable his life support against Rutledge’s orders. Stevens back aboard the train he disarms the bomb, immobilize Frost before the train destroy. After 8 minutes, stevens kisses and the time seems to freeze and Goodwin turns off his life support per his request Steven. Steven was surprised he was still in the same Fentress and his minds still remains. Stevens and Christina goes out for their Coffee and visit to cloud Gate in Chicago’s AT&T Plaza and live happily ever after, and then Goodwin arriving to work earlier that morning she receive and email from stevens explaining that he has changed the course of the future by saving the passengers. And that the comatose soldier in the lab will eventually go on to a different first Source Code mission one day.

Advantages:

Through using the Source Code we can use this Experimental Device to prevent an incident easily.

Disadvantages:

But through this Device Source Code, it can suffer a person, because instead that person having he’s rest in peace but they just given a task.

          Reflection:

The movie was created successfully it can go to virtual life because he/she ca n make changes in certain time. When we used programming we can easily and safety make our daily life. Nothing is impossible in programming it can make a changes.

3. Evens, Odds, and Dozens: Create a program that will count down to 0 from a given number—$start.  For each number, print the number and then print (“ is even”) if it is even and (“ is odd”), if it is odd.  In addition, if the number is a multiple of 12, print the number of dozens that it represents.  For example if $start=27, the output might look like:
26 is even.
25 is odd.
24 is even.  24 is 2 dozen.
23 is odd. … 

27 is odd.

Answer :

function OddEven($testNum)

{

if($testNum % 2 == 0)

{

echo " is Even";

}

else

{

echo " is Odd";

}

}

$start = 20;

do

{

echo $start <br>;

OddEven($start);

$start--;

}

while($start>=1)

 2. “Mod” calculation: The mod (%) operator in PHP calculates the remainder when $a is divided by $b.  Create a program that calculates the remainder by repeatedly subtracting $b from $a until it can no longer be subtracted (i.e. stop subtracting when $a is less than $b).  Print out the remainder, nicely formatted (e.g. if $a=7 and $b=2 you might print “7 mod 2 = 1”). 

Answer:

function mod($modB)
{
if($modB % 2 == 0)
{
echo "0";
}
else
{
echo "1";
}
}
$a = 2;
$b = 7;
do
{
echo '$b % $a =';
mod($b);
$b -= $a;
}
while($b > 1)

1. Leap Year Calculation: Given a variable called $year, create a program that will print out “<xxxx> is a leap year” or “<xxxx> is not a leap year” (where <xxxx> is the value of $year).  Use the following rules to determine if a year is a leap year:  if the year is divisible by 4 then it is a leap year, unless it is also divisible by 100 (in which case it is not a leap year), unless it is divisible by 400 (in which case it is a leap year). 

Answer:

 $year = 2012;
if($year % 4 == 0)
{
if($year % 100 == 0)
  {
if($year % 400 == 0)
  {
  echo "Leapyear";
    }
else
{
echo "Not a Leapyear";
}
   }
else
{
echo "Leapyear";
